Abstract

The present application provides a positive active material, a positive electrode and a lithium-ion battery. The positive active material comprising a first particle and a second particle, wherein the first particle has a chemical formula of Li<sub>e</sub>Co<sub>g</sub>M<sub>1-g</sub>O<sub>2-i</sub>, and the second particle has a chemical formula of Li<sub>f</sub>Co<sub>h</sub>N<sub>1-h</sub>O<sub>2-j</sub>, the element M is at least two selected from a group consisting of Ni, Mn, Al, Mg, Ti, La, Y and Zr, the element N is at least one selected from a group consisting of Ni, Mn, Al, Mg, Ti, La, Y and Zr, and 0.8≤e≤1.2, 0<g<1, -0.1<i<0.2, 0.8<f<1.2, 0<h<1, -0.1≤j≤0.2, the number of types of the element M in the first particle is greater than the number of types of the element N in the second particles.. The present application stabilizes the first particles and the second particles by adjusting the type and content of the doping elements in the first particle and in the second particle, so that the capacity retention rate of the lithium-ion battery is improved.
